ROTARY EXPLOSION-ENGINE.

Specification of Letters Patent.

Application filed February 5, 1909. Serial No. 476,291.

' are supported on the main shaft and are caused to rotate about saidshaft through the reaction exerted by a fixed roller path on the pistonrods of the cylinders.

According to the invention, there are sixteen motor cylinders and aspecial roller path is employed characterized by the fact that curvesare formed so as to' present eight equidistant points near to the axisof rotation and eight equidistant points farther away from said axis,the difference between a the distance of the farthest points to the axisand the distance of the nearest points to the a roller axis being equalto the stroke of the pistons.

In the accompanying drawings, Figure 1 is a sectional elevation view ofthe engine, Fig. 2 is a cross section on line X X of Fig.

' 1, and Fig. 3 is a diagrammatic view of the roller path. Fig. 4 is aview taken at right angles to the plane of Fig. 2.

he main shaft a has keyed to it a polygonal'part or drum 6 with sixteenfaces on each, of which is fixed by means of bolts a cylinder 0. Each ofthese cylinders has cast integral therewith a segment of an annulus, allthese segments, fixed together by means of bolts constituting a completeannulus.

Each piston d carries a roller 9 loosely mounted on a stud f supportedby two ears Ii. h solid with the piston.

The rollers g are adapted to roll against (path 9' formed of steel castin one piece an having a U cross section. This roller path can be fixedto any suitable frame. The rolling band on which bear the rollers of theistons is slightly projecting. The form of t e roller path is determinedin such manner as to give the best output; to this end the parts of theroller path corresponding to the compression are formed by gentl slopingcurves, so as to give a slow an progressive compression, and the artscorresponding to the expansion are ormed by rapidly sloping curves so asto gives. very active expansion.

. g, of the distributingX The casing is closed at the sides by twopieces of sheet-metal k k which have central apertures for allowing therotation and cooling of the cylinders. These metalsheets are secured-bysmall bolts Z to the rolling way 7'. a

The shaft a is carried by two bearing supports m m with four arms fixedto the ro ling way j by means of bolts.

To each cylinder corresponds in the part b a chamber 41. extended by. aconduit 0 leading to the side of the distribution. During the rotationof the en ine, the ports 0 pass successively in front 0 correspondingrts plate r. The resh gases-are supplied to t eadmission ports 72 bypipes s and the burned gases escape through pipes 25 leadin to theexhaust ports 9. The distributing p ate 1 has two threaded stems itwhich shde in two corresponding holes of the bearing support m. .Thesestems u hold the plate in place and prevent it from revolving. Spiralsprings v mounted on the stems u and bearing on the support m force thedistribution plate to bear energetically on the rotating part 6.

Into each chamber n corresponding to a cylinder projects the end of asparking plug Patented-Jan. 25, 1910.

w connected to a bronze contact :0 fixed to the periphery of a circularebonite plate 1 keyed to the shaft; the sixteen bronze contacts a; passsuccessively, during the rotation in front of two pairs of small bronzerollers z z mounted at the end of ebonite stems 1 articulated on pivots2 carried by the casing; the rollers z z are caused to bear agalnst theplate 3 by means of a sprin 3 and are electrically connected to one of te poles of a suitable-source of electric current such as a high tensionmagneto electric machine.

In front of the plate y is mounted loosely on the main shaft anotherebonite plate 4 on which are attached two terminals 5. and 6 connectedto the second pole of .the source of current. Two springs 7 and 8 fixedto the ebonite plate 4 carry two bronze rollers 9 and 10 against whichbear the teeth of a pinion 11 keyed on the main shaft; these teeth bymoving the springs apart through the medium of the rollers, put them incontact with the screws 5 and 6. The hi h tension current flows thenfrom one po e of the source throu h the four rollers a a, the fourcorrespon mg contacts :12, the four corresponding sparking plugs,whereby an ignitin spark is simultaneousl produced,

in the our corresponding cylin ers, the metallic body of the motor, theshaft a, the pinion 11, the rollers 9, 10, the springs 7 8, theterminals 5, 6, and the second pole of the source. The spark ceases whenthe springs 7 and 8 leave the terminals and 6. When the four contactsfollowing those above referred to, come next under the four rollers a z,a spark is simultaneously produced in the four following cylinders andso on, so that the sixteen cylinders are fired in every fourth of arevolution, four being fired at the same time.

To explain the operation of the engine,

it is only necessary to study theoperation' of one cylinder. Supposethat the roller of a piston is at the point A of the roller path: atthis point the explosion is produced in the corresponding cylinder andthe piston and orces the piston to return into the cylinadmission portp.

der. During this time the port 0- of the cylinder passes in front of theport q of the .di'stributing plate 7' and the exhaust of the burnedgases is produced. From C to D the piston is no longer guided bythe'roller path: the centrifugal force alone causes it to bear on saidpath and to cause the suction owing tothe passage of the port 0- infront of the At D the compression commences and lasts until A isreached. When the roller of the piston reaches the point A the ignitionroller touches the contact :1: corresponding to the sparking plug of thecylinder: the tooth pinion 11 in its rotation produces the s ark, theexplosion is produced in the cylin er and the operations previouslydescribed are repeated...

It will be understood by referring to the drawin that an explosion isproduced simultaneous y at four points A that is to say in fourcylinders at the same time, and four cameo times per cylinder and perrevolution. Be-

.t-WQQlltWO successive omts A each cylinder accomplishes a comp etecycle: from A to B useful work; from B to C exhaust; from C to D"suction and from D to A compression and ignition. Each cylinder ivingfour explosions per revolution, there 1s thus for the sixteen cylinders,sixty-four explosions per revolution. The distributing plate hasconsequently four admission openings and four exhaust openings.

The operation of an engine constructed according to this invention isvery regular; the dead points are avoided and on account of thecontinuity of the engine efforts, the respective dimensions of all theparts may be very much reduced, which gives a great lightness with agreat regularity.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is:

A rotary explosion engine comprising in combination a motor shaft, apolygonal drum with sixteen faces keyed on said motor shaft, a radiatingcylinder. secured respectively one on each face of the polygonal drum, apiston arranged in each. cylinder, means for the admission of freshgases into the cylinders, means for the exhaust of the burned gases,means for igniting the fresh gases in the cylinders, rollers carried bythe outer ends of the piston rods and a stationary roller path on whichare adapted to roll the said rollers and having a curved shapepresenting eight equidistant points nearto the axis of rotation andeight equidistant points farther away from said axis, the differencebetween the distance of the farthest points to the axis and the distanceof the nearest points to the axis being equal to the stroke of thepistons, substantially as described and for the purpose set forth.

In testimony whereof I have signed my v name to this specification inthe presence of two subscribing witnesses.
